Hey Kevin - Happy to!!
The process is very similar and there really aren't any major differences:
1) Open 'Windows Live Movie Maker' and click on the Project
tab [from the top menu]. Now under "Aspect Ratio", make sure the Widescreen (16:9)
option is selected [highlighted].
2) Click on the "Click here to browse for videos and and photos" text in the center of the main panel. Browse to the location of the required video file, highlight it and then click Open
3) Click on the Home
tab [from the top menu]. Now in the ribbon menu you will see an option to Save Movie
(it's the second last menu item on the far right of the ribbon).
4) Click on "Save Movie" and from the drop down menu select "Burn a DVD".
That's it, you are good to go.
P.S. Post back if anything needs clarifying [I can post screenshots if need be]
